ARTIFICIAL-TOOTH MOUNTING.

Application filed May 10,

To all whom it may concern:

Be it Known that I, HUGO H. KnnUs, a citizen of he United States, and aresident of the city of Chicago, county of Cook, and State of lilinois,have invented certain new and useful improvements in Artificial- ToothMountings, of which the following is a specification.

My invention relates to improvements in artificial tooth mountings andhas for its object the provision of an improved construction of thischaracter by means of which artificial teeth may be readily and securelymounted,

A further and particular object of my invention is to provide astructure of the class mentioned wherein the artificial teeth aredirectly connected to the bridge without the interposition of metallicor similar elements.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understood by reference to the accompanyingdrawings forming a part of this specification, and in which,

Fig. 1 is a top plan view of a tooth mounting embodying my invention,

Fig. 2, a side elevation of the same.

Fig. 3, a. View similar to Fig. 2 with the artificial teeth removed,

Fig. 4, a top plan view corresponding with Fig. 3,

Fig. 5, a side view of an artificial tooth employed in the constructionillustrated in Figs. 1 to 4.,

Fig. 6, an inner face view of said tooth,

Fig. 7, a bottom plan view of a modified form of construction,

Fig, 8, a front view of the same.

Fig. 9, a view similar to Fig. 7, but with the artificial teeth removed,

Fig. 10, a View similar to Fig. 8 with the artificial teeth removed,

Fig. 11, a side view of one of the teeth employed in the constructionillustrated in Figs. 7 to 10, and

Fig. 12-, an inner face view of the construction illustrated in Fig. 11.

The form of construction illustrated in Figs. 1 to 6 inclusive,comprises a. bridge 13 having tooth crowns or caps 14 and 15 located atthe ends thereof and adapted to fitover and be adhesively secured to thecorresponding teeth in the human jaw, the

191?. Serial No. 167,766.

construction illustrated being adapted for use in mounting thecorresponding teeth in the lower right jaw. Tooth receiving sockets 16are provided on the top of the bridge 18, are open on their outsides andare provided with securing flanges 17 on their lateral edges. Theartificial teeth to be mounted are in the form of shallow bodies 18 and18 adapted to fit the respective sockets 16. and having their upper orexposed surfaces 19 roughened or indented to imitate the natural surfaceof the corre sponding teeth, Each of the bodies 18 is provided on itssides with grooves 20 adapted to fit over the corresponding flanges 17and with a depending apron 21 adapted to overhang the outer side of thebody 13 to imitate the corresponding portions of the natural teeth.

In use, the crowns 14 and 15 are fitted to the corresponding teeth inthe jaw and are secured thereover by suitable cement or other adhesive,the artificial teeth 18 and 18 being secured in the bridge as indicated.By this arrangement, the pressure on the teeth is transmitted directlyto the bridge, inasmuch as the bodies of the teeth are mounted on thepressure side of the bridge, that is, the side of the bridge to whichthe pressure is directly applied in chewing.

The form of construction illustrated in Figs. 7 to 12 inclusive, isadapted for use in replacing the upper incisors or front teeth. In thisconstruction, a bridge 22 is provided with tooth crowns or caps 23 and24 at its ends adapted to fit over the corresponding incisors just asbefore. The bridge 24: is provided on its outer face with toothreceiving sockets 25 having upwardly converging securing fianges 26 attheir sides. The teeth 27 to be inserted are provided on their rearsides with grooves 28 to fit the flanges 26 and with an abutment 29fitting against the lower or pressure edge of the bridge 24, so that thechewing pressure is transmitted directly to said bridge. The mounting issecured in place substantially as above outlined.

While I have illustrated and described the preferred forms ofconstruction for carrying my invention into effect, these are capable ofvariation and modification without departing from the spirit of theinvention. 1, therefore. do not wish to be limited to the precisedetails of construction set forth, but

desire to avail myself of such variations and modifications as comewithin the scope of the appended claims.

Having described my invention What I claim as new and desire to secureby Letters Patent is:

1. An artificial tooth mounting comprising a bridge, socket in the faceof the bridge, securing flanges on the sides of said socket intermediatethe bottom and outer edges thereof, a tooth slidably fitting said socketand provided with grooves fitting said flanges and abutment on saidtooth contacting With the bridge, the abutting faces thereof being inthe path of the greatest pressure and at substantially right anglesthereto, substantially as described.

2. A device as set forth in claim 1 in which the securing flanges aresubstantially parallel to the bottom of the socket, substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
